Asparagus spears (Asparagus officinalis L.) stored 28 days at 2C in air, a flow-through controlled-atmosphere (CA) system, or 14 days in polymeric film consumer packages were evaluated in respect to compositional and quality changes. CA-stored spears retained more sugars, organic acids, and soluble proteins than spears stored in air. Spears stored in vented consumer packages had a useful life of 14 days, whereas those in nonvented packages started to break down after 8 days. Spears from vented packages lost more weight but retained more sugars and organic acids than those from nonvented packages.
